SPECIFICATION forming part of Letters Patent No. 717,672, dated January 6, 1903. Application iiled April 5. 1902. Serial No. 101,459. (No model.)

To all when?, tm/Cty concern:

Be itrknown that l, AUGUST GARTNER, of Reserve township, in the county of Allegheny and State of Pennsylvania, have invented a certain new and useful Improvement in Hod- Elevators, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a front elevation of 1n y improved bod-elevator. Fig. 2 is a side elevation of the same, and Fig. 3 is an end view of the hoisting-drum. Fig. 4 is a view showing a modi# ication. V

Like symbols of reference indicate like parts wherever they occur.

My invention relates to an improvement in hoisting-elevators for use in the erection of buildings; and it has for itsobject an elevator which will serve to carry and deliverhodsof brick, mortar, or other material rapidly and without waste of time or labor to the story being built and at the same time adapted to be changed and adjusted to dierent heights or stories without any change of or cutting of the ropes or hoisting-cables and without undue expenditure of time and'labor in making such change in height.

To this end it consists of a drum mounted on a suitable frame or foundation at the starting-point or ground-floor, a frame or bearing adapted to support aV shaft carrying sheaves or band-wheels, this frame being movable in order to enable it to be carried to suitable supports arranged at various heights or stories, the wheel-supporting shaft being capable of one or more ropes or cables, both ends of which are secured to the circumference of the drum and partially coiled thereon in coils, the loop or standing part of the rope or ropes passing over the sheave on the upper shaft and adapted to be coiled and uncoiled on the drum by the rotation thereof, and bod-supporting cross-bars extending between the standing parts of the ropes, a double-action reversible engine or motor being geared'to the hoisting-drum for operating the same, as is hereinafter" more fully described.

In the drawings, 2 represents the hoistingdrum, which is mounted on suitable bearings 3 on the ground-door and is provided with a gear-wheel Ll, by means of which it is connected with and adapted to be driven by any suitable double-acting reversible engine or motor. On the circumference of the drum 2 are collars 5, which are secured to the drum by the tightening -bolts 6 Y and are preferably arranged at the ends of the drum and at points toward the middle. To eyes on these bolts or to other suitable securing devices the two ends of the wire-ropes 7 and Saro made fast, A

part of the ropes being wound around the circumference of the drum. The standing part of these ropes extends from the coils 9 and 10 to and over the sheaves or wheels 11 and 12, and lars 5, to which the other ends of the ropes are secured. Instead of two ropes one continuous rope may be employed, it being secured at its middle to the middle collars, as shown at d in Fig. Ll. The construction otherwise is the same as that illustrated in Figs. 1 and 2. These sheaves 11 and 12 are keyed to the shaft 18, which is jonrnaled in the journal-blocks 1i, which journal-blocks are so adjustably mounted in the standards 15 that they maybe moved by the adjustingscrews 16 in order to adjust the shaft and sheaves sufficiently to tauteu the ropes. The standards 15 are supported by the beams 17, which beamsmay be the `floor-beams of the different stories or beams of scaffolding arranged at any desired height. In order to move the standards 15 upward as the building grows in height, it is only necessary to throw some of the coils of rope from the drum 2, thereby lengthening the standing parts of the ropes, and to place the standards on other supporting-beams at agreaterheight from the ground.

Extending between and secured to the ropes 7 and 8 are the hed-carrying bars 1S and 19, which serve to support the hods for carrying brick, mortar, or other material. Hooks 2O maybe fixed to the bars for supporting buckets of water. e

The operation of my bod-elevator is as follows: The apparatus having'been set in position, the upper standards being at the height to deliver the material at the desired point, the engine or motor is started, causing one end of the ropes to wind and the other end to unwind on the drum 2, thereby carrying the thence down to the middle colbod-supporting bar and full hods upward on one side of the drum and the bod-supporting bars and empty hods downward on the other side of the drum. Vhen the full hods are emptied and the empty hods are filled, the engine or motor is reversed and the hods are again carried upward and downward by the winding and uuwinding ofthe ropes -7 and 8 on the drum 2. As the building grows in height the standing parts of the ropes are lengthened in the manner already described.

The advantages of my invention will be apparent to those skilled in the art. The apparatus may be operated by an engine or motor of small size and power, and it can be adjusted to different heights without any cuttingr or changing of the ropes or cables other than the throwing of a certain number of coils from the drum.

What I claim is- In a hod-elevator, the combination of a drum, a frame carrying sheaves, said frame being movable with relation to the drum and drum-supports, ropes, both ends of which are secured to the drum and the standing parts passed over the sheaves, and adapted to wind and unwind on the drum, and bod-carrying supports secured to the ropes; substantially as speciied.

2. In a bod-elevator, the combination of a drum, a frame carrying a shaft, said frame being movable with relation to the drum and drum-supports, sheaves mounted on said shaft, adjusting-screws, ropes, both ends of which are secured to the drum and the standing parts passed over the sheaves, and adapted to wind and unwind on the drum, and hodcarrying supports secured to the ropes; substantially as specified.

3. In a hud-elevator, the combination of a drum, a frame carrying sheaves, said frame being movable relatively to the drum and drum-supports, flexible means secured to the drum and passing over said sheaves and adapted to wind and unwind on and from the drum, and bod-carrying supports secured to said iiexible means; substantially as described.

In testimony whereof I have `hereunto set my hand.

AUGUST GARTNER.
